Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is proffesor-for-testing/agentic-qe's own configuration. It tells Claude Code and Codex how to work on agentic-qe itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-qe configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

V3 Security Overhaul scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

V3 Security Overhaul

What This Skill Does

Orchestrates comprehensive security overhaul for claude-flow v3, addressing critical vulnerabilities and establishing security-first development practices using specialized v3 security agents.

Quick Start

# Initialize V3 security domain (parallel)
Task("Security architecture", "Design v3 threat model and security boundaries", "v3-security-architect")
Task("CVE remediation", "Fix CVE-1, CVE-2, CVE-3 critical vulnerabilities", "security-auditor")
Task("Security testing", "Implement TDD London School security framework", "test-architect")

Critical Security Fixes

CVE-1: Vulnerable Dependencies

npm update @anthropic-ai$claude-code@^2.0.31
npm audit --audit-level high

CVE-2: Weak Password Hashing

// ❌ Old: SHA-256 with hardcoded salt
const hash = crypto.createHash('sha256').update(password + salt).digest('hex');

// ✅ New: bcrypt with 12 rounds
import bcrypt from 'bcrypt';
const hash = await bcrypt.hash(password, 12);

CVE-3: Hardcoded Credentials

// ✅ Generate secure random credentials
const apiKey = crypto.randomBytes(32).toString('hex');

Security Patterns

Input Validation (Zod)

import { z } from 'zod';

const TaskSchema = z.object({
  taskId: z.string().uuid(),
  content: z.string().max(10000),
  agentType: z.enum(['security', 'core', 'integration'])
});

Path Sanitization

function securePath(userPath: string, allowedPrefix: string): string {
  const resolved = path.resolve(allowedPrefix, userPath);
  if (!resolved.startsWith(path.resolve(allowedPrefix))) {
    throw new SecurityError('Path traversal detected');
  }
  return resolved;
}

Safe Command Execution

import { execFile } from 'child_process';

// ✅ Safe: No shell interpretation
const { stdout } = await execFile('git', [userInput], { shell: false });

Success Metrics

  • Security Score: 90/100 (npm audit + custom scans)
  • CVE Resolution: 100% of critical vulnerabilities fixed
  • Test Coverage: >95% security-critical code
  • Implementation: All secure patterns documented and tested

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

V3 Security Overhaul is a skill published in the GitHub repository proffesor-for-testing/agentic-qe (475 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 592 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). It is 100% identical to V3 Security Overhaul, differing in 2 lines, and is treated as a copy.
